To all whom it may condemn Be it known that I W'IIJJAM O. Bimf'ron, Jr.,a citizen of the 'b'nited States,'res1 dm at Manoa, county of Delaware,and State 0 Pennsylvania, have invented a new and useful Improvement inContact Makers and Interrupters' for Ignition Systems, of which thefollowin' is a; full, clear, and exact descriptiomme erence being had tothe accompanyifig drawings, which form a part of. this specification.

The object of my invention is to prov de an rovedmeans fori opening andclos ng ry, circuit in a single spark ignition system for automobiles.

A .The nature of the invention will be understood by reference to theaccompanying drawings, which show several preferred .em-- bodiments of minvention and in,\vhich-- Figure 1 is a 'egram of the electricalconneotions of an ign tionsystem to which m "h t c axis of the shaftwhich 'actuates t e contact maker. Figs. 3,4 and 5 are detail views,inside elevation, of three difierent contact makers y invention; 6 is aplan view of the contact maker of 1g. 5. D

A. step 27 prevents the lever 14' frommoving ina direction o'p' osite tothe normal direction of travel of e pins 22, but in the event'ofthereverse movement ofthefl ins, the'head 26 will move independently o thelever, due to its spring connection therewith, until the actunting'pinoverridesthe mo to normal posiion. 7 The lever 14 is normally heldagainstthe- StO FhQT by means of a ring 28 end of'thc lever.

In the rotetionof the cam shaft, the pins 22 strike the head 26 therebytilting the lever 24 and causing-the beveled end of-its extens'i0n29 tocontact with and slide upon Y and beyond the beveled end of lever 31;This operation causes the up er end of lever. 31 to dip toward andcgcmst contact- 35"- and momentarily closethe primary circuit d.- Atthis time the shaft l-i'hes turned 'into such position that. the outerend bf the distributer conductor" g is in pro er relation to i one ofthe binding posts 1,- ,3 and 4, '50
